Imagine if Paul McCartney or John Lennon forgot the melody to ‘Hey Jude’ or ‘Strawberry Fields’. The world would be deprived of masterpieces. Musicians out there need a backup so that their masterpieces don’t slip into the ether. A Gibson Memory Cable ($150) records up to 13 hours of music to Micro SD cards. Plug it into a guitar, PA mixer or any cable output and never worry about losing a great idea.
